油桐尺蠖核型多角体病毒（BsSNPV）是一种高致病力的病毒株，生物测定nPIB（LC50）=1．657×104mL．经过全国7个省20多个单位联合试验，生物统计结果表明：BsSNPV防治第1代油桐尺蠖虫口下降率为97．2％；防治第2代油桐尺蠖虫口下降宰为93．97％；F测验其t值为0．184，小于理论t0．05（29）＝2．045．优于敌百虫、DDVP、辛硫磷和BT等农药是一种杀虫效果稳定、使用安全、经济有效的生物杀虫剂．
Tung Karsch nuclear polyhedrosis virus (BsSNPV) is a highly pathogenic strain of virus, bioassay nPIB (LC50) = 1.657 × 104mL. Through the joint experiment of more than 20 units in 7 provinces in China, the biometric results showed that the rate of decline of the first generation Triticum aestivum treated with BsSNPV was 97.2% and that of the second generation Triticum aestivum was 93.97%. The F test has a t value of 0.184, which is less than the theoretical t0.05 (29) = 2.045. Better than trichlorfon, DDVP, phoxim and BT and other pesticides is a insecticidal insecticidal effect of stable, safe and cost-effective.
